Product Description

The A.H. Systems ECF-12K is a precision Equivalent Capacitance Fixture (ECSM) engineered for the accurate verification and calibration of active monopole antennas. Operating across a wide frequency range of 100 Hz to 60 MHz, this 12-pF capacitive fixture simulates the self-capacitance of the monopole rod element, ensuring the matching network maintains the correct source impedance for measurement receivers. Specifically designed to meet the rigorous requirements of MIL-STD 461, ANSI C63.5:2017, and CISPR 16-1-6:2017, the ECF-12K eliminates stray capacitance and measurement errors common in non-standard voltage dividing fixtures. Featuring a rugged construction, precision BNC connectors, and a standard 1/4-20 threaded mount, the ECF-12K is an indispensable tool for labs requiring repeatable, standards-compliant antenna performance checks.

Other fixtures are available as an option. The 10pF capacitator (model ECF-10K) is available and only recommended when following older standards.
